Abstract

A power cable conduit (1) for installation underground, comprises an outer pipe (2), a sleeve (3) of synthetic plastics material located coaxially, or generally so, with respect to the pipe (2), with the sleeve (3) separated by spacers (5) from the internal surface (6) of the pipe to define a first-annulus; a central tube (8), also located co-axially, or generally so, with respect to the pipe (2) and also of synthetic plastics material, located within the sleeve (3), with central tube (8) spaced from the internal surface (10) of the sleeve (3) to define a second annulus (11); a plurality of cable tubes (12) of synthetic plastics material located in an array around the external periphery (9) of the central tube (8); a plurality of electrical power cables (13) each extending, with clearance, along some or all of the cable tubes (12); with the central tube (8) being adapted to convey a heat transfer medium and with the cable tubes (13) and/or the second annulus (11) being adapted to convey heat transfer medium therealong. The invention also includes both a method of installing an underground power cable conduit, and also an underground electrical power transmission system.
